These projects include those subject to (BAAQMD Regulation 2-5), the BAAQMD Regulation 2-2-304 , 40 CFR 51.116). The intent of the modeling analysis is to demonstrate that emissions from a given facility or project do not or will not adversely impact the maintenance of air quality standards in the BAAQMD; be it acceptable levels of toxic air contaminants (TAC), the California or National Ambient Air Quality Standards (AAQS), or applicable PSD increments. For permit applications involving air toxics, modeling may be required as part of a health risk screening analysis (HRSA). In most cases this modeling is performed by the BAAQMD with input from the applicant. For projects where the applicant is responsible for modeling, in particular for a PSD analysis, the BAAQMD

Emission dispersion modelling through program Fluidyn-PANACHE and MODIM Program Fluidyn-PANACHE Program description Fluidyn-PANACHE is a computing program of the French firm Transoft Int. that uses the model CFD, based on laws of conservation of energy, mass and momentum. Program Fluidyn-PANACHE is determined for dispersion of pollutants, escaping into environmental air during different climatic and geographic conditions. It enables simulation of the following effects: short and long-term influence of pollutants simulation of accidental conditions and determination of anticipated dispersion of pollutants Input data terrain specification (geographic position, type of built-up area, terrain characteristics, e.g. forests, waters, vegetation) specification of source and pollutants (chimney, spot planar or volumetric source and its geometry; selection of components from the data base or entry of required characteristics for new components) specification of weather (wind - velocity, direction, velocity profile, condition of surrounding - temperature, pressure).
